;DEMOUNTABLE RIM.

Application filed May 23,1921.

To all whom it may concern.

Be it known thatI, TOM'MOORE BENNETT, a citizen of theU'nite'd States, residing at 300 Vest 54th St.,;borough of Manhattan, New York and State ot New York, have invented certain new and useful Improvements in Demountable Rims, 0t which the following isa specification.

The present invention relates to demountable rims for vehicle wheels and of; that character which permits-the carrying anin- 'flated pneumatic tire on the demountable rim when the latter is on or ott the telly ot the wheel. r

The principal objects of the invention are, xto w provide a demoun table rim so constructed-that the tire maybe readily assemhle'd ontherim-whenthe same is wholly ottth'e telly ot' the wheel or when a; 'art of the rim is on-the telly and under w ich latter condition the wheel constitutes a-suppo-r't tor the rim part while the tire is being moved or forced thereonto; to provide a 'circumterentially divided demountable rim which may be dismembered and assembled without the springing'o't portions thereof as is usually "necessary in connection with transversely split rims, thus making it possible to arrange the rim tor'the reception or removal ot thetire without the dangers incident touse ot su ch transvers'ely split rims; a d to provide --'demountable rims which are eflicie'nt as aretaining means tor the tire, heat in" appearance and inexpensive to manufacture. Y i

Another object;ot'the invention 'is to provide a demountab'le -rim which may be secured t o' the usual type o't wheel'telly ring by wedges, bolts and-nuts without alterationth'ereot; or in other words replace-the type of transversely split rims n'o'w in common use without thenecessity of altering the wheel telly portion nor discardingfthe retaining wedges or lugs now in common use.

Qt her objects and advantages ot the invention will-appear in the'tollowing de tailed description taken in connection with the-accompanying drawings torminga part o tthi's specification, and in which drawings: V V v Fig'ijre l is a face view ot a wheel equipped with a demountab'le rim con siir uct-ed according to my invention with a pneematic tirethereen; i

the flange D thereof; and" vices carriedLby the telly Badapted to retain the rim F in place-on thew-heel main Serial No. 471,638.

Fig.2 is an enlarged fragmentary transverse sectional view on the linei2-,2 ot Figure 1 through: the rim only.v

F ig.'3 is a face view ot the parts of the rim dismembered, one 'part" being settoone side to disclose details.

Fig. 4 is an enlarged view'partly in transverse section through the wheel telly and demountalole rim and partly in -pe rspective.

in the drawings where similar reference vto similarparts throughcharacters reter out the views: Aqdesignates a wheel main body p'ortion including a telly and telly ring C, having a flange D -at one edge; .E a tire, F a demountable rim constructed according to the principle of myv invention adapted'flto beslid onto ring Cand engage G retainin'g debody portion.

In "the example shownfthe" Wheel main bo'c yportion A is shown as comprising va hubf); and spokes 6,;in addition tothe telly B and telly ring C, btittliis' is*inerelyby way of; example, tor the demountable rim, may be applied to wheels er types other than-"those having spokes, such as disc wheels, or so ,caiidmm Wheels, where'the ring C,- constitutes the telly I p The demountable rim -'F comprises two annular members 7 and 8, provided with flanges ."9 and 10, respectively, in the e2:-

ample shown, shaped tor'engagement with the sides of so called straight sidetires; and retaining devices adapted to hold the annular members 7 and .8 against "circumferential 'movementone with respect to the other, and against axial movement of one with respect to the other;

In the example shown, the annular memher 7 maybe consideredas the major .mem

v her, and the annularmember 8 as the minor member; the tormerhavinga relatively wide collarlike port-ion 12, from which the flange 9 extends, while the member 8 is provided with a relatively narrow portionfl3' trom which flange 10 extends. JIn. practice the collar like portion 12 extends" substantially the width otthe telly ring and where members '7 and 8 abut, the tormer maybe convex as indicated at 14 while the other may be concave, as clearly shownin Figure 2 otthe drawings, so as to fit snugly; H Each retaining device 11 preferably comprises a hinge member 16, comprising leaves 17 and 18, and a pintle 19; a screw threaded stem 20 carried by the flange 10, extending from the outer face thereof, this stem extending through a slot 21 in leaf 18 {and a Y nut 22 for stem 20.

v the drawings.

The leaf 17 of each hinge member 16 may be secured to the rim portion 12, in any suitable manner, such as by rivets 23, and it is preferred to provide, at the internal periphery of rim portion 12, recesses 24, receiving a portion of'each leaf 17, but in a manner that the leaf projects inwardly of the internal periphery of rim member 7, to act as a spacer between the felly ring C and the annular rim member 7, as clearly shown in Figure 4: of the drawings. It is also preferred to bevel the inner end of leaf 17, as indicated at 25 to facilitate moving of the demountable rim to operative relation on the wheel main body portion A. The hinge memberv 16 may simulate, to quite some extent, an ordinary hinge, in which the leaf 17 is provided with spaced apart sleeves 25, while the leaf 18 is provided with a sleeve 26, fitting between the sleeves 25, these sleeves receiving the pintle 19. When disposing the hinged members into fixed rela tion to the annular member 7 these sleeves are arranged to project inwardly toward the axis of the annular member, so that the leaf 18 may be swung toward said axis, as indicateddby dotted lines in Figure 2 of the drawings, and whereby no obstruction is presented for movement of the annular member 8 toward or from annular member 7. The leaf 17 constitutes a projection extending laterally from the annular member 7, and in order to aid in preventing circumferential movement of annular'member 8 with respect to member 7, the former may be provided with a plurality of spaced apart recesses 27, one for each retaining device 11, the'hinge leaves 17 or projections of the annular member 7 fitting into these recesses 27. The hinged leaves 18 may be shaped to conform to the outer contour of flange 10 and may be provided with hooked end portions 28 to engage over the lip 29 of flange 10, as clearly shownin Figures 2 and 1 of These hooked portions of the leaves 18 not only aid in retaining the annular member 8 in proper relation to annular member 7, but also constitute projec tions which may be readily engaged by a tool for the purpose of swinging these leaves toward or from annular member 8.

' The screw threaded stems 20 may be formed integral with the annular member 8, or may be secured thereto in any suitable manner. The slot 21 may extend so as to open to the free end portions of the leaves 18, so as to permit of the removal of mud, clay, or tar, which may accumulate in the Slot, 1.-

In practice, it is to be observed, that tire E, may be disposed in operative. relation to the demountable rim F, and inflated, no matter whether the demountable rim is on or off the wheel main body portion A. Spare telly ring C, for with the retaining devices j G, carried by the felly, either removed, or swung out of the path of movement of annular member 8, and the removal of the nuts 22, and swinging ofthe'leaves 18 to the dotted position shown in Figure 2 of the drawings, or, as shown in Figure 3 ofthe drawings, the annular member 8 'may be easily removed or replaced, the annular member 7 remaining on the wheel main body portion, which latter acts as a support when forcing the tire casing onto the annular member 7. :7

The retaining devices'G may be of any suitable character adapted 'to prevent axial movement of the demountable rim with respect to the wheel main body portion. 7

Changes in detailsmay bemade without departing from the "spirit of this invention or the scope of the claims.
